這兩天更新完Xcode8之后發(fā)現(xiàn)Xcode對圖標的要求又有了變化，之前用的一個小應用“IconKit”還沒趕上節(jié)奏，已經(jīng)不能滿足Xcode8的要求了。

于是就想起來用Python自己做個腳本來生成圖標。

其實這個腳本很早就寫了，現(xiàn)在為了適應iOS10，就修改完善下，并且放到了GitHub。

可以看看效果圖：

腳本環(huán)境要求

Python 2.7

PIL or Pillow

筆者親測，也許是筆者太菜，試了各種方法安裝PIL總是出錯，最后還是用了Pillow，效果一樣的。

怎么使用腳本

在Windows的命令行或者Mac的終端，輸入:

python tool.py [action] [filename] [platform]
action：icon 或者 screenshot
filename：圖標文件名，截屏不需要文件名，自動遍歷
platform：ios 或者 android

舉一些例子：

生成iOS的圖標：python tool.py icon icon.jpg ios

生成安卓的圖標：python tool.py icon icon.jpg android

生成iOS的截屏：python tool.py screenshot ios

生成安卓的截屏：python tool.py screenshot android

注意：

生成安卓圓角圖標需要一張PNG來裁剪，尺寸512x512，70圓角，GitHub中已經(jīng)附帶。

生成截屏時會自動遍歷所有JPG和PNG文件，自動識別橫豎屏
